The Effect of Discovery Learning Model on the Ability to Understand Mathematical Concepts of Grade VII Students of SMP Negeri 1 Bengkulu City

This study aimed to investigate the effect of the Discovery Learning model on students' conceptual understanding. Discovery learning has been identified as a teaching model that encourages active exploration and deep understanding, which can influence both students' mathematical conceptual understanding and attitudes towards mathematics. The type of research conducted was a quasi-experimental research with a posttest- only control group design. The population in this study was all seventh-grade students of SMP Negeri 1 city of Bengkulu in the 2023/2024 school year. In this study, the Simple Random Sampling technique was used, resulting in class VII.5 being the experimental class and class VII.6 being the control class, with each class consisting of 30 students.
